    "It gives me peace of mind". A new perspective on the identification of quality cues on salmon fillet products in Japan and the USA2022In: Aquaculture, ISSN 0044-8486, E-ISSN 1873-5622, Vol. 554Article in journal (Refereed)
    Abstract [en]

    The way in which perceived quality affects consumer food choice is complex due to variations in intrinsic and extrinsic product attributes that interface with personal factors and the socio-cultural context. Taking the example of salmon fillets sold in the USA and Japan, this study uses a think-aloud protocol (TAP) as a data collection method and a corpus (text data)-driven approach as an analytical tool for uncovering how consumers infer quality cues on salmon fillets. The study aims to help in designing representative studies and may help in explaining survey results. The findings indicate that consumers infer quality under the influence of multiple factors, including individual knowledge of food production, processing and cooking, personal preferences based on culinary heritage and the socio-cultural environment. This study also shows how a TAP can be used in combination with text mining to provide richer insights into consumer choice.

    Marine yeast (Candida sake) cultured on herring brine side streams is a promising feed ingredient and omega-3 source for rainbow trout (Oncorhynchus mykiss)2023In: Aquaculture, ISSN 0044-8486, E-ISSN 1873-5622, Vol. 571, article id 739448Article in journal (Refereed)
    Abstract [en]

    A major challenge for the aquaculture industry is the supply of sustainable feeds. A promising model to achieve this is to utilize circular flows where feed ingredients, such as single cell protein, are cultivated using side streams of the food industry. The aim of this study was to evaluate the marine yeast Candida sake, produced on herring brine side streams, as a source of protein and immune stimulant in feed for salmonid fish. The dry C. sake product contained 54% protein (3.3% lysine and 0.8% methionine) and 13% lipids (1.1% eicosapentaenoic, EPA, and 1% docosahexaenoic acid, DHA). Four experimental diets were designed and tested in a 9-week feeding trial using juvenile rainbow trout (Oncorhynchus mykiss). A control diet containing both fish and plant-based ingredients constituted the base feed to which 20% (to evaluate effects on digestibility, growth and intestinal physiology), 20% heat-treated (to evaluate effects of downstream processing) and 3% (to evaluate immune stimulatory properties, replacing 3% soy protein concentrate) C. sake was added. The apparent digestibility coefficient of C. sake for protein, fat and gross energy was above 80%, and for amino acids above 90% regardless of treatment, suggesting a high bioavailability of C. sake. All three yeast containing diets performed equally to the control regarding specific growth rate, feed conversion ratio and functional intestinal health. These results suggest that C. sake is a promising alternative protein source for circular feeds in the salmonid industry. The presence of EPA and DHA represents an added value. The heat treatment increased the apparent digestibility coefficient of dry matter by 8% but decreased amino acid digestibility by on average 3%, indicating that heat treatment may not be the optimal downstream processing technique. Furthermore, the inclusion of 3% C. sake increased the intestinal lamina propria width and TGF-β transcription, indicating an immune stimulating effect. Future research is needed to understand these immune modulatory effects of C. sake supplementation. © 2023 The Authors

    Greenhouse gas emission reduction opportunities for the Norwegian salmon farming sector - can they outweigh growth?2024In: Aquaculture, ISSN 0044-8486, E-ISSN 1873-5622, Vol. 581, article id 740431Article in journal (Refereed)
    Abstract [en]

    Norwegian farmed Atlantic salmon is a nutritious type of food in increasing demand and although production has stagnated and is faced by various challenges, it is likely to continue to expand in the future. We present results from a detailed greenhouse gas emission assessment of the most important Norwegian farmed salmon export products along with improvement measures. By scaling up both baseline results and reduction opportunities, based on growth projections, we estimate current and future emissions of the sector as a whole. We show that export of gutted salmon to Europe by truck dominates Norwegian salmon exports, not only in volume and value, but also in emissions, followed by export of fresh gutted salmon and fillets to Asia and fillets to the US by air. The cumulative greenhouse gas emissions are dominated by feed production followed by emissions from overseas airfreighting of fresh products. The five most important emission reduction measures, based only on existing technology and without particular order were 1) slightly increased feed efficiency, 2) increased utilization of side streams occurring in secondary processing after export, 3) seafreight to market instead of road and air, 4) higher energy efficiency and cleaner energy sources, and 5) changed feed composition. Collectively, they have the potential to reduce greenhouse gas emissions of current production by 60%, from 5.2 to 2.1 million tonnes of CO2e, assuming the same relative importance of each supply chain. This implies that a medium growth-scenario, representing more than a doubling of the volume of salmon farmed to 3.3 million tonnes, would be possible while reducing total sector emissions by 16% if the improvement measures were fully implemented. For larger reductions, either lower growth or more ambitious implementation of improvement measures is needed. Although greenhouse gas emissions are often linked to resource efficiency and wider sustainability, this is not always the case, and it is important to avoid shifting burdens from climate to e.g. eutrophication or biodiversity impacts. However, many environmental impacts of salmon farming are centered around feed efficiency, and even problems with welfare, escapees, and in part eutrophication are reflected in lower feed efficiency resulting in higher greenhouse gas emissions. In addition to the systematic collection of robust data for more continuous monitoring of greenhouse gas emission performance over time, we therefore recommend identifying additional indicators to monitor to ensure the sector develops not only towards climate neutrality but also towards broader sustainability.
